PN 4006 MIDTERM EXAM 2026–2027 | (50
QUESTIONS AND CORRECT ANSWERS) |
ALREADY GRADED A+ | 100% VERIFIED
Introduction
This structured PN 4006 Midterm Exam format for 2026–2027 provides the complete
layout for generating high-quality exam-style questions with correct answers and
rationales. It emphasizes clinical judgment, patient safety, medical-surgical nursing
principles, and evidence-based practice critical to professional nursing practice and
successful course completion.
1. An older adult patient is at higher risk for fluid volume deficit primarily because of
which physiological change?
A. Increased thirst mechanism
B. Decreased muscle mass and increased body fat
C. Improved kidney concentration ability
D. Increased total body water percentage
Rationale: Muscle tissue holds more water than fat tissue. As people age, muscle mass
typically declines and fat increases, leading to lower total body water and a higher risk of
dehydration.
2. A nurse is assessing a patient with a suspected GI bleed. Which clinical
manifestation is most indicative of fluid volume deficit?
A. Bounding peripheral pulses
B. Moist oral mucosa
C. Dry mouth and poor skin turgor
D. Hypertension
Rationale: Fluid loss from a GI bleed leads to systemic dehydration; dry mucous
membranes and decreased skin elasticity are classic signs of extracellular fluid volume
depletion.
,3. If the extracellular fluid (ECF) becomes hypertonic compared to the intracellular
fluid (ICF), what will happen to the cells?
A. Water will enter the cells, causing them to swell
B. Water will exit the cells, causing them to shrink
C. There will be no movement of water
D. Electrolytes will move into the cells to equalize pressure
Rationale: In a hypertonic environment, the concentration of solutes is higher outside the
cell, drawing water out of the cell via osmosis.
4. A patient has a serum sodium level of 128 mEq/L. Which nursing intervention is
most appropriate?
A. Increase oral water intake
B. Limit water intake (fluid restriction)
C. Administer a potent loop diuretic
D. Encourage a low-sodium diet
Rationale: Hyponatremia is often dilutional. Restricting free water intake helps increase
the concentration of sodium in the blood.
5. Which patient condition would the nurse identify as a significant risk factor for
developing hypermagnesemia?
A. Diarrhea
B. Chronic renal failure
C. Hyperthyroidism
D. Excessive sweating
Rationale: The kidneys are responsible for excreting magnesium. In renal failure, the ability
to clear magnesium is impaired, leading to toxic accumulations.
6. A nurse observes a twitch in the patient's facial muscles when tapping the cheek in
front of the ear. How should the nurse document this finding?
, A. Trousseau sign
B. Babinski sign
C. Chvostek sign
D. Romberg sign
Rationale: A positive Chvostek sign is a classic clinical indicator of hypocalcemia (low
serum calcium levels).
7. Following a total thyroidectomy, for which clinical sign should the nurse monitor to
detect accidental parathyroid gland removal?
A. Negative Chvostek sign
B. Bradycardia
C. Positive Chvostek sign
D. Hypertension
Rationale: The parathyroid glands regulate calcium. Accidental removal or damage during
thyroid surgery leads to hypocalcemia, manifesting as a positive Chvostek sign.
8. How do the lungs act as an acid-base buffer when blood CO2 levels are high?
A. By decreasing respiratory rate to retain acid
B. By increasing respiratory rate and depth to blow off CO2
C. By secreting bicarbonate into the bloodstream
D. By decreasing depth of respirations
Rationale: The respiratory system compensates for acidosis by increasing ventilation to
eliminate carbon dioxide, which reduces the carbonic acid load in the blood.
9. A patient's arterial blood gas (ABG) result shows a pH of 7.50. This value indicates:
A. Acidosis
B. Alkalosis
C. Normal pH
